Denyhosts Alternatives
Denyhosts is described as 'The idea of denying access to SSH servers is nothing new and I was inspired by many other scripts that I discovered. However, none of them did things the way I envisioned them to. Also, they were all shell scripts which do not offer the elegance of Python' and is an app in the network & admin category. There are more than 10 alternatives to Denyhosts for a variety of platforms, including Linux, Windows, Self-Hosted, Mac and Web-based apps. The best Denyhosts alternative is CrowdSec. It's not free, so if you're looking for a free alternative, you could try CrowdSec or Fail2ban. Other great apps like Denyhosts are IPBanPro, reaction, RdpGuard and IPQ BDB.

21 Fail2ban alternativesFail2ban scans log files (e.g. /var/log/apache/error_log) and bans IPs that show the malicious signs -- too many password failures, seeking for exploits, etc. Generally Fail2Ban is then used to update firewall rules to reject the IP addresses for a specified amount of time...
SSHGuard monitors services through their logging activity. It reacts to messages about dangerous activity by blocking the source address with the local firewall. SSHGuard employs a clever parser that can transparently recognize several logging formats at once (syslog, syslog-ng...
IPBan is a FREE and open source application that allows auto banning ip addresses from failed login attempts. Many sources are watched such as SSH, SMTP, SQL-Server, MySQL, RDP and dropped packets.
15 RdpGuard alternativesRdpGuard allows you to protect your Remote Desktop (RDP) from brute-force attacks by blocking attacker's IP address. Fail2Ban for Windows.
IPQ BDB filtering is done by a user space netfilter daemon that issues verdicts after looking up the IP address in a Berkeley DB. The fuzzy blocking model, freely inspired by STOCKADE, is designed to block non-distributed dictionary attacks and mitigate spam.
